BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates generally to an exercise system and morespecifically it relates to an interactive exercise instruction systemand method for providing interactive multimedia information to anexerciser and for providing the exerciser the ability to provideinformation back to the system before, during or after exercising.

Description of the Related Art

Any discussion of the related art throughout the specification should inno way be considered as an admission that such related art is widelyknown or forms part of common general knowledge in the field.

Conventional Pilates apparatuses are well known throughout the fitnessindustry, and are generally comprised of a rectangular frame supportedon the floor at various points of contact about the rectangular frame. APilates apparatus is generally adjustable in a variety of ways withregard to both the size (e.g., height) of the exerciser, as well as theparticular exercise being performed.

This adjustability of the Pilates apparatus may be of benefit so as toaccommodate exercisers of varying sizes and with varying exercisetargets. However, this same adjustability may become a detriment to newusers of the Pilates apparatus or when the Pilates apparatus is used ina class taught by a Pilates instructor. In such situations, a Pilatesinstructor needs to make sure each exerciser's machine is set upproperly and that they are performing each exercise correctly. This maybecome a burden on the instructor, especially as the class size grows.

Further, each exerciser may need to monitor not only their form withoutspecific guidance from the instructor (who may be busy assisting otherexercisers), but also monitor their speed and intensity of workout. Thisself-monitoring, if done improperly, can cause injury or the exerciserto experience lesser results compared to that which they may haveachieved in the same or even less time were the exercises performedproperly.

Because of the inherent problems with the related art, there is a needfor a new and improved interactive exercise instruction system andmethod for providing interactive multimedia information to an exerciserand for providing the exerciser the ability to provide information backto the system before, during or after exercising.

BRIEF SUMMARY OF THE INVENTION

Provided herein is an exercise system which includes receiving aselection of an exercise to perform on an exercise machine, displaying avisual indicator on the exercise surface indicating where on theexercise surface the exerciser is to make contact to perform theselected exercise, determining whether the contact area corresponds to alocation of the visual indicator on the exercise surface and determiningas to whether or not the exerciser is properly positioned to perform theexercise as signaled.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 is a block diagram of an exercise apparatus 1 (e.g. a Pilatesapparatus), according to an embodiment. The exercise apparatus 1 may becomprised of various types of exercise machines such as, but not limitedto, Pilates machines, rowing machines, weight lifting machines, and thelike. The exercise apparatus 1 may be comprised of the exercise machinedescribed and shown in U.S. Pat. No. 8,641,585, issued on Feb. 4, 2014to Sebastien Lagree and U.S. Pat. No. 7,803,095 to Sebastien Lagree,which are hereby fully incorporated herein by reference.

A Pilates apparatus is an adjustable exercise machine that can beadjusted to suit people of varying ages, sizes and fitness goals. Theapparatus may often be found in a gym or in a Pilates studio that isused for conducting a Pilates class for a group of exercisers each ontheir own apparatus. The Pilates apparatus (including its resistances,positions and accessories) may be individually adjusted by eachexerciser to accommodate their personal needs or to conform to whateverexercise is being performed in the class.

However, one drawback of this adjustability of a conventional Pilatesapparatus is that it takes a long time to learn or to have an instructorindividually instruct the exercisers in a class as to proper set upand/or performance of an exercise. For example, a Pilates instructor mayneed to individually instruct students on the proper positioning oftheir bodies upon the apparatus, the proper settings for resistancesprings, the proper adjustment positioning of attached accessories, andinstruction on the proper method of performing an exercise. The loss ofactual workout time can result in lower revenue for the gym or class,and penalizes the exercisers in the class by reducing the actual workouttime available to the class. This problem may be further exacerbated ifdifferent exercises are performed that require additional adjustments tothe apparatus during the class.

Another drawback of conventional Pilates apparatuses is that they areunable to provide feedback to the exerciser during the performance of anexercise. For example, as an exerciser performs multiple repetitions ofan exercise (as is typically performed during an exercise session) theapparatus is unable to communicate with the exerciser as to theirperformance. For example, the apparatus cannot inform the exerciser asto the number of repetitions completed, whether they are performing theexercise properly, or whether they are performing repetitions tooslowly, too fast, or timed perfectly.

A conventional Pilates apparatus is also unable to provide visualinstruction on how to properly perform the various segments of anexercise, leaving this level of instruction to the instructor. Properlyperforming each phase of an exercise may require the exerciser to beinformed about their posture, how to properly breathe during each phase,what muscles to concentrate on flexing, and how far the exerciser shouldstretch or flex their body during each segment of the exercise. Anindividual instructor would find it difficult to closely monitor theperformance of an exercise over an entire class, especially as the classsize grows. An improperly performed exercise can, however, lead tosubpar results or even injury by the exerciser.

In the example of FIG. 1, a Pilates apparatus 1 comprises a processor 2that facilitates transmission, processing and management ofcommunication with a user interface 4 that may be integrated into one ormore exercise surfaces of the apparatus 1. User interface 4 may includeany display screen, including a touchscreen or interactive display. Inan embodiment, user interface 4 may be a touch screen interactivedisplay that is capable of being activated to sense a contact with anexerciser.

User interface 4 may include any type of display screen capable ofreceiving user input (via a touch screen or other input device) and/oroutputting video and/or audio. For example, input devices by which toreceive user or exerciser input (herein “user” and “exerciser” are usedinterchangeably) may include an analog switch, keyboard, or a touchscreen affixed to or otherwise connected to the apparatus 1.

In an embodiment, user interface 4 may include a touch screen integratedinto an exercise surface of apparatus 1 that receives input from a user.For example, user interface 4 may display an icon or indicator (e.g.,visual indicator) as to where a user is to place their feet or otherbody part on exercise surface/user interface 4 to perform a selectedexercise. A user may then step, kneel, or otherwise make contact withuser interface 4. Apparatus 1 may be able to detect a location of thecontact area with the user, and how closely the contact area correspondsto the displayed area of contact for performance of the exercise.

User interface 4 may include a display including a digital userinterface 4 that receives input from and provides output to a user. Forexample, user interface 4 may provide menus, buttons, or other displayitems that may be selected (e.g., via touch or other selectionmechanism) to activate various functions. For example, functions includeloading or requesting an exercise or sequence of exercises, exerciseinstructions for set up or performance of an exercise, generalinformation (such as information regarding the operation of apparatus 1or safety guidelines) from the library 7. In an embodiment, apparatus 1may communicate with (e.g., provide information to and/or retrieveinformation from) a user's personal storage device 8 such as asmartphone, USB card, or personal physiological tracking device.

As just referenced, library 7 may be a storage device containinginformation, such as instructions, videos, audio, or other multimediafor instructing the user how to set up, use, and/or perform one or moreexercises on apparatus 1. In an embodiment, the library storage device 7may be remote from the processor 2 and accessible over one or morenetworks. The information (instructions, directions, etc.) from library7 may then be output or displayed on one or more user interfaces 4.

As just referenced, the information of library 7 may provideinstructions to an exerciser on how to properly adjust the apparatus 1,including settings to perform one or more exercises. The information mayalso include instructions on how an exerciser should position themselfon apparatus 1 to properly perform an exercise or exercise sequence. Forexample, user interface 4 may be integrated into an exercise surface ofapparatus 1. Then for example, the information from library 7 mayindicate a portion of the user interface 4 to illuminate or otherwiseupon which to display visual indicators as to how the user is toposition him/herself on apparatus 1. In an embodiment, user interface 4may indicate where the exerciser is to place their hands, feet, knees,or other body part to properly position themselves to perform a selectedexercise, whereby the user is to place their body on user interface 4itself at the indicated location(s).

Before or during an exercise, apparatus 1 may monitor where and when anexerciser makes contact (e.g., with a foot, hand, etc.) with userinterface 4. Data relating to the exerciser's actual position may begenerated or compared relative to a display area where the user was tomake contact with user interface 4 to properly perform the exercise. Ifthe received data indicates that the exerciser has assumed an improperposition upon the exercise surface (based on a misalignment or lack ofcorrespondence between the user's contact and the indicated portion ofthe display), the processor 2 may signal the exerciser their position isimproper. For example, apparatus 1 may provide instructions on how tocorrect, change, or otherwise modify their position to positionthemselves properly to perform the exercise. These instructions mayinclude visual, audio, and/or tactile indicators or signals to theexerciser.

In an embodiment, apparatus 1 may determine a new position of theexerciser based on a subsequent contact with user interface 4, forexample, during a performance of the exercise. Based on the subsequentcontact, processor 2 may determine whether or not the exerciser is nowproperly positioned to perform the exercise based on the exerciser's newcontact area relative to the indicated or displayed (or previouslydisplayed) preferred position area. Apparatus 1 may then inform the useras just described if their subsequent positioning is correct orincorrect.

Real-time instructional information or exercise performance data may bedisplayed for or otherwise provided to the exerciser before, during, orafter the performance of an exercise. In an embodiment, if the exerciseris positioned upon the user interface 4 such that the displayedinformation is not viewable or otherwise, the user interface 4 isdisplaying positional information where the exerciser is to make contactwith the user interface 4 to perform the exercise, the additional orinstructional information may be delivered to an alternate userinterface 4 installed on a different surface of apparatus 1 or viaanother device with a visible screen such as a personal storage device 8or, for example, audio instructions may be provided.

In an embodiment, apparatus 1 may communicate with or otherwise becommunicatively coupled to a personal storage device 8. For example,apparatus 1 and personal storage device 8 may communicate via a directplug-in or wired connection, wireless connection through the Internet,cellular network, Bluetooth pairing, or other communication links.Personal storage device 8 may be a wearable activity-tracking devicethat collects or senses physiological or other information regarding anexerciser's activity or performance. In an embodiment, information maybe provided from apparatus 1 for display on a screen or user interfaceof personal storage device 8, or from personal storage device 8 fordisplay on a user interface 4 of apparatus 1. For example, physiologicalinformation may be retrieved from device 8 and displayed on userinterface 4.

In an embodiment, information (such as instructions from library 7 orpersonal data) may be displayed via personal storage device 8. Forexample, a personal storage device 8, such as a smartphone, may includean app or application that communicates with apparatus 1 and can be usedto communicate with an exerciser. Through the app or other communicativelink, instructional information or other data may be provided to anddisplayed on personal storage device 8.

FIG. 2 is a block diagram of a Pilates apparatus 1 configured tocommunicate over a network 6, according to an embodiment.

Apparatus 1 may include one or more user interfaces 4. In an embodiment,apparatus 1 may include multiple user interfaces 4 of varying types. Forexample, a first user interface 4 may be a touch screen display, while asecond user interface 4 may be a monitor or other video/audio-outputdevice. Processor 2 may provide for communications between apparatus 1and one or more network devices operating on or otherwise communicatingover network 6. An example network device may include, library storagedevice 7 that may contain information to be displayed on the one or moreuser interfaces 4 integrated into or otherwise in communication with theapparatus 1.

Network 6 may include any communications link or network. For example,network 6 may include a Bluetooth, LAN, WIFI, cellular network, WAN, orwired communication link between Pilates apparatus 1 and one or moredevices (e.g., personal storage device 8, library storage device 7, orother data source 10). Other data source 10 may include or providecontent such as a television feed, the Internet, or music that isintended to be displayed upon or otherwise output by one or more userinterfaces 4 of apparatus 1. In an embodiment, any of the devices shownto communicate with apparatus 1 over network 6 may communicate directlywith or otherwise be integrated with processor 2.

Further, the overall functionality of the interactive exercise apparatus1 of FIG. 2 may be similar to that described above with respect toFIG. 1. However, FIG. 2 is an example embodiment of the apparatus 1communicatively coupled to various components (e.g., storage device,other content or data source 10, and personal storage device 8) over anetwork 6.

FIG. 3 is a block diagram of exemplary communications between a userinterface 4 and a Pilates apparatus 1.

Pilates apparatus 1 may be similar to the apparatus 1 described abovewith respect to FIG. 1 and FIG. 2, and may have a processor 2. Processor2 may communicate with a user via a user interface 4, including bothproviding information to (visual/audio output) and receiving informationfrom a user. The communications may occur in real-time.

In an embodiment, an exerciser may communicate or otherwise interactwith the interactive exercise instruction system (as may be integratedwith or operating on processor 2) of Pilates apparatus 1 through one ormore user interfaces 4. FIG. 3 shows various examples of user interfaces4 that may be used to facilitate communication with an exerciser. Invarying embodiments, an apparatus 1 may include one or more of the userinterfaces 4.

In an embodiment, user interface 4 may include a keyboard or analogswitch 32 that may be used to actuate and/or otherwise interact with thesystem. Actuating the system or apparatus 1 may include the process ofturning on or waking up the system for use by an exerciser. A keyboard32 may comprise a touch screen or an accessible switch affixed tootherwise connected or in communication with the Pilates apparatus 1 andcorresponding to a display. In an embodiment, keyboard 32 may include astandard or specialized keyboard with a wired/wireless connection toapparatus 1.

In an embodiment, a user or exerciser may use a mobile device 31 tocommunicate with apparatus 1. For example, mobile device 31 may have aninstalled application (e.g., app) that communicates with a program orsystem operating on processor 2 of apparatus 1. Via the installedapplication or other communication link (such as Bluetooth), theexerciser may remotely communicate with and/or control apparatus 1. Forexample, an exerciser using a specially designed app installed on theirmobile device 31 may control or communicate with the Pilates apparatus 1as described herein, including selecting which exercise to perform. Inan embodiment, an exerciser may actuate the interactive exerciseinstruction system of apparatus 1 from their mobile device 31.

Once actuated, the interactive exercise system of the Pilates apparatus1 may function as a virtual instructor or coach. As described above,apparatus 1 may visually and/or audibly provide instructions to properlyset up the Pilates apparatus 1 to perform a Pilates exercise via one ormore of the user interfaces 4. As such, use of the interactive exercisesystem of the Pilates apparatus 1 may minimize injury resulting fromexercising on an improperly set-up apparatus. In an embodiment,apparatus 1 may alert an exerciser if it senses (via one or more of theuser interfaces 4) that a user is not properly performing or properlypositioned to perform an exercise, and as such may prevent injury thatmay occur from the improper performance of an exercise.

As referenced above, in an embodiment, user interface 4 may be aninteractive touch screen 33. Interactive touch screen 33 may include oneor more interactive touch screens 33 of Pilates apparatus 1. Userinterface 4 (including interactive touch screen 33) may displayinstructions for exercisers as to on what body part to place on theexercise surface of Pilates apparatus 1 and where to place that bodypart. For example, an interactive display or touch screen 33 may beintegrated with or otherwise connected to the exercise surface of aslidable carriage (or other surface) of Pilates apparatus 1. The displaymay provide text or other visual/audible instructions as to where theexerciser should position their hands, feet, knees, or other body partupon the carriage, and further illuminate the proper location forrespective body part. For example, the touch screen 33 may provide anindicator or image of where to place the left and/or right foot.

An exerciser, receiving the instructions, may step on or otherwiseposition themselves on apparatus 1 (e.g., on user interface 4 integratedinto an exercise surface of apparatus 1) as instructed. User interface 4may be activated, now acting as a touch screen 33, may sense thelocation of the exerciser's feet or other body part on the exercisesurface/user interface 4. The user interface 4 or processor 2 mayanalyze the contact location (e.g., where the exerciser placed his/herfeet on user interface 4) relative to the instructed or displayedlocation(s). Apparatus 1 may then determine that the user is properlypositioned (e.g., if the user has placed their feet in the properlocation(s)) or improperly positioned (e.g., if the user has not placedone or more feet in the proper location(s)) to perform a selectedexercise.

In an embodiment, apparatus 1 (e.g., via user interface 4) mayaudibly/visually alert the exerciser to relocate their feet to theproper location to perform a selected exercise. Or, for example, theapparatus 1 may inform the user if their feet are properly positioned onthe apparatus 1 and that they may begin the exercise.

In an embodiment, user interface 4 may include or be part of a wearablesensor 30. Wearable sensor 30 may track physical activities, foodintake, and physiological functions such as respiration, heart rate andblood pressure of an exerciser. These activities may occur inconjunction with or apart from use of Pilates apparatus 1. For example,processor 2 may receive a beginning (pre-exercise) heartbeat and a postand/or during exercise heartbeat of the user.

In an embodiment, the interactive exercise instruction system ofapparatus 1 provides for a real-time user interface 4 or interaction viawearable sensor 30. When attached to the exerciser, in wired or wirelesscommunication with the processor 2, the exerciser's performance data iscommunicated to one or more of the user interfaces 4 to receivereal-time data and/or provide instant performance feedback. In anembodiment, the performance data or feedback may include data regardingthe user's physiological status during a performance of an exercise orset of exercises.

Based on standardized performance data previously entered into adatabase (not shown), the interactive exercise instruction system ofapparatus 1 may function as a coach, informing the exerciser of theirperformance. For example, sensors may determine that the exerciser isperforming the exercise repetitions too quickly, and apparatus 1 maysignal or send a message for the exerciser to slow down. As justreferenced, another example of real-time feedback may be based on heartrate sensor information. For example, processor 2, referencing astandardized heart rate table, may determine that the exerciser is onlyperforming at 65% of their aerobic capacity, and instruct the exerciserto increase exercise intensity by increasing the spring resistanceworkload or pace.

Via contact between an exerciser and user interface 4 at one or morepoints of contact, the system of apparatus 1 may continually monitor,instruct, and correct an exerciser in the performance one or morePilates exercises. This information may be provided both before and/orduring the performance of an exercise, and in real-time. The system mayeliminate or reduce time instructors spend on one-on-one coaching ofstudents in a Pilates class, reduce injuries related to improperpositioning or performance of an exercise, and provide beneficialperformance feedback to help exercisers maximize the value of theirexercise time.

FIG. 4 is an exemplary diagram of a Pilates apparatus 1 with aninteractive video display device 50 integrated into an exercise surface.Display devices 48, 49, and 50 may include functionality similar to thatdescribed above with respect to user interface 4, and may includevarying embodiments thereof. For example, display 50 may be atouchscreen device, while display 48 is a monitor (video-out) displaywithout touch screen functionality.

Pilates apparatus 1 may have a lower support structure comprising aplurality of supports 41 that support a pair of parallel rails 42extending substantially the length of the apparatus 1. A slidablecarriage 43 may slide along the parallel rails 42 in response toexerciser movements. For example, an exerciser may perform exercises bymoving slidable carriage 43 along the rails in a direction distal to theend of the apparatus 1.

A variable resistance force may be generated by attaching or adjustingone or more removable springs 44 between the slidable carriage 43 and asubstantially fixed end 45 of the lower structure. An exerciser may workagainst the resistance of the springs 44 by applying a workload forcethat exceeds the spring resistance force. The workload force may beapplied to the slidable carriage 43, such that the slidable carriageslides along the rails 42 in a direction opposed to the fixed end 45.

For example, an exerciser kneeling on the slidable carriage 43, facingthe fixed end 45, may grasp the push handle 47 with two hands, and pushagainst the push handle 47 with sufficient force to overcome theresistance force of the springs 44 thereby sliding the slidable carriage43 away from the fixed end 45. The exerciser, after extending the push,may reduce pressure on the push handle 47, thereby allowing the springs44 to pull the slidable carriage 43 back towards the fixed end 45. Thisback and forth, or complete cycle, may be referred to as “onerepetition” of the exercise. Typically, Pilates exercise routines callfor the exerciser to complete a fixed number of repetitions, forexample, “ten reps”, before beginning a new and different exercise.

In the embodiment shown, a video display screen 50 may be integratedinto the top exercise surface of the slidable carriage 43. Displayscreen 50 may be designed to sustain the weight or force applied by auser who is standing, sitting, or otherwise contacting the displayscreen 50 before, during, and/or after an exercise. The video displayscreen 50 may be display only or a touch screen that provides forviewing and interaction by an exerciser. In an embodiment, the videodisplay screen 50 may first present to an exerciser text or videoinstructions relating to general safety considerations prior toexercising or instructions on how to perform the upcoming exercise.

After reviewing the instructions, the exerciser may interact with thevideo display screen 50 to advance the information to be shown next onthe touch display screen, or alternatively, may touch a “next button” ona secondary interactive screen 49 positioned within easy reach in asecondary location on the exercise surface.

Pilates apparatus 1, having a stationary exercise surface affixed to thestructure at the fixed end 45, shows one possible location of a thirdvideo display screen 48, which may be a video or touch screen as well.

In an embodiment, the video display screens 48, 49, 50 may be flexible,thereby providing comfort and resilience on the top exercise surfaces.For example, the display screens may have the approximate comfort andresilience of the material of the exercise surfaces or a differentlevel. In different embodiments, the size and number of display screensmay vary in different embodiments.

Pilates apparatus 1 includes an integrated multimedia input/outputdevice for delivering instruction, information, entertainment, andexercise performance to an exerciser, and receiving manual or automaticinput from an exerciser is provided.

As described, Pilates apparatus 1 may include one or more video displayscreens 48, 49, 50 (which may include interactive video display screens48, 49, 50 with or without touch-screen user interfaces and audiocapabilities). The information provided via the display screens mayinclude, but is not limited to, exercise instruction, informationrelating to the exerciser's membership at an exercise facility, generalexercise information, monitoring and reporting exerciser performanceinformation in real time, and entertainment such as television, radioprogramming or advertising.

Additional information received from one or more other sources (asdescribed above) may also be displayed on the display screens ofapparatus 1. For example, aerobic performance, anaerobic performance,cardiovascular performance including pulse and blood pressure, andperformance against maximum thresholds may be provided to an exerciser.Exercisers who are continually informed of their performance levelsthroughout the exercise will understand whether to “back off” orincrease the intensity in order to maximize the physiological benefitsof the exercise.

Pilates apparatus 1 may more efficiently deliver exercise instructionsto a multitude of participants within a Pilates class, reduce injurythrough continued monitoring and feedback instruction, reduce the totaltime required to conduct a class, and thereby increase the number ofclasses and associated revenue for the Pilates facility. For example,the Pilates apparatus 1 may be synchronized amongst the machines of theclass, such that each exerciser is receiving information regarding thesame exercise as being performed by the class. As described above,Pilates apparatus 1 may be connected to a network, and may exchange(send and/or receive) information with one or more devices over thenetwork 6.

In an embodiment, Pilates apparatus 1 may access personal data of theexerciser (e.g., from a local or network storage), and display or outputvideo, audio, or text portions of the exerciser's personal data throughthe video or audio devices incorporated into the apparatus 1, such asdisplay devices 48, 49, 50. This may be performed via networkcommunications. In an embodiment, Pilates apparatus 1 may communicatewith a wearable activity or physiological tracking device 30 worn by auser or an interactive mobile application installed on a personal mobiledevice 31 (or other communication link between mobile device 31 andapparatus 1).

Pilates apparatus 1 provides an interactive display screen (e.g.,display 50) integrated into one or more exercise surfaces of theapparatus such that the exerciser's position can be automaticallydetermined by contact with screen 50. The position information may beprocessed to determine an accuracy or correctness of the exerciser'sposition on apparatus 1. Additionally, instructions relating to properrepositioning (if needed) alerts the exerciser via a video and/or audiooutput via apparatus 1 or other personal device of the exerciser,thereby eliminating the requirement for an instructor to individuallyinstruct each exerciser in a multi-exerciser class, and further reducingthe potential for injury of an exerciser improperly positioned upon theapparatus 1.

FIG. 5 is an exemplary diagram showing a top view of a Pilates apparatus1. The example apparatus 1 is a top view of the apparatus 1 of FIG. 4and includes multiple video displays 48, 49, 50 integrated into varioussurfaces (including an exercise surface, display 50) of apparatus 1.

In the example embodiment, one video display screen 48 may be integratedinto the fixed end of the apparatus 1, and two video display screens 49,50 may be integrated into the exercise surface of the slidable carriage43. Other embodiments may include a varying number of displays mountedon varying surfaces of apparatus 1. Before, during and after exercising,certain safety, instructional, or exerciser performance data may bedisplayed on one or more of the display screens 48, 49, 50. In anembodiment, apparatus 1 may include speakers or audio out capabilitiesin addition to or in lieu of the display screens 48, 49, 50.

Some of the displayed content may be automatically shown on the displayscreens 48, 49, 50, some of the information may be displayed responsiveto exerciser input or menu selection, and some of the informationdisplayed may be real-time exerciser performance data sent to theapparatus 1 from wearable tracking devices 30. For example, if apparatus1 receives information indicating the exerciser's heart beat is toofast, apparatus 1 may alert the exerciser to slow down or stopexercising.

In different embodiments, the source from which content or informationis received may vary, as may the manner in which instructions aredelivered to the user. Further, although displayed content has beendescribed as being visual content, in embodiments, visual content mayinclude visual and audio content, audio only, or other multimediacontent. Audio content, such as the audio track of displayed videos, orstreaming music for example, may also be delivered to speakers (notshown) integrated into or otherwise associated with apparatus 1. Itshould be further noted that audio may alternatively be delivered to theexerciser using a wired headset/speakers or wireless (e.g., Bluetooth)connected wireless device with appropriate speakers or personal headset.

In an embodiment, one or more of the display screens 48, 49, 50 may be atouch interface. For example, an image of a right foot 51 and an imageof a left foot 52 may be digital representations of proper footplacement for a particular exercise. The representations may beilluminated or otherwise displayed on the interactive display screen 50.An exerciser, preparing to position themselves on the slidable carriage43 for an exercise to be performed, may then place their left and rightfoot over the illuminated locations. In an embodiment, apparatus 1 mayprovide audio content and/or text content in addition to the displayedrepresentations.

Display 50 shows an example of a location where a user is to place theirfeet to properly position themselves to perform a particular exercise onapparatus 1. Touch screen 50 may sense an exerciser's foot location andsend the location information to a processor 2 to determine whether theexerciser is properly positioned on the slidable carriage 43 for theupcoming exercise. If the exerciser is not properly positioned,instructions regarding re-positioning the feet may be delivered back tothe exerciser by way of video, audio, or other multimedia. When theexerciser's feet are properly positioned, the user may similarly bealerted. For example, the information displayed may change frompositioning information, to instructions on performing the exercise, oranother indicator of proper placement may be signaled to the user, suchas a green light or audible alert.

FIG. 6 is an exemplary diagram showing a top view of a slidable carriage43 of a Pilates apparatus 1, according to an embodiment. The exampleapparatus 1 may include one or more video display devices 48, 49, 50attached to or integrated into the exercise surface.

The display screen 50 shows another example of how an exerciser is toposition themselves to perform another exercise on a Pilates apparatus.Screen 50 is mounted on the top of slidable carriage 43 and shows wherea user is place their left and right knees and in which direction theuser should be faced. For example, the user should be faced to be ableto read the text displayed on screen 50. Screen 50 displays a locationof where an exerciser's body part(s) is to be placed, which body part isto be placed on exercise surface/screen 50 and in which direction theexerciser should be faced to perform a selected exercise.

The apparatus 1 may process a contact area where a user places theirknees relative to the displayed area where the user is to place theirknees. If the knees are improperly placed, the text instructions 60, aswell as the knee images 61 may change to alert the exerciser of improperpositioning. However, if it is determined that the exerciser's knees areproperly positioned for the upcoming exercise, the information displayedon a second touch sensitive display screen 49 may change to anilluminated representation of a “start” button 62. The exerciser startsthe exercise routine thereafter either by touching the “start” button 62or beginning to move in performance of the exercise on apparatus 1.

The “start” button 62 may be displayed on any one or more of a pluralityof interactive display screens 49 or alternatively, the exercise routinemay automatically start without exerciser input other than the touchsensitive display screen 50 and processor 2 sensing that the exerciser'sknees are properly positioned for the exercise. In an embodiment, theexerciser may be provided an visual and/or audible alert indicatingwhether or not they are properly positioned before the exercise begins,and/or may be provided a subsequent alert if they deviate from theproper position during a performance of the exercise.

FIGS. 7A and 7B are exemplary diagrams showing a side view of twopositions of an exerciser performing an exercise upon a Pilatesapparatus 1. In FIG. 7A, an exerciser 70 is positioned upon a Pilatesapparatus 1 with a right knee and lower leg placed upon the slidablecarriage 43, a left foot placed at a stationary location upon the floor,and hands grasping a push handle 47 affixed to the stationary end ofapparatus 1. By way of example, the exerciser may be wearing anactivity-tracking device 71. Device 71 may be similar to wearable sensor30.

Device 71 may be in communication with apparatus 1. For example,apparatus 1 may receive real-time physiological information from device71, while device 71 receives alerts or notifications from apparatus 1regarding the user's performance of the exercise (e.g., regardingposition or rate of exercise). The wearable tracking device 71 is shownat a certain vertical distance above the floor, indicated by thehorizontal line A.

A representative top view of an interactive display device 50 of theslidable carriage 43 is shown. The image shown in display 50 is anexample of what may be displayed on carriage 43 (e.g., the display 50 onor integrated with carriage 43) before/during the user's performance ofthe exercise. The text and image instructions may indicate or instructthe user where to place their knee and hands in preparation of theexercise. The exerciser in the top illustration is shown with the rightknee extended away from the stationary exercise platform end 45 of theapparatus 1, having used exercise force to move the slidable carriage 43against the spring resistance means 44. In this position, the exerciserhas completed five and one-half repetitions of the exercise as indicatedby display 72 (which may be integrated into a different portion ofapparatus 1 visible to user) or may be displayed on device 71. Thisdisplay 72 may include any performance information includingrepetitions, heartbeat, speed, calorie count, time, or otherinformation.

In FIG. 7B, exerciser 71 has returned to the starting position of theexercise by lowering workforce applied to the hands and right leg,thereby allowing the slidable carriage 43, in response to the springbiasing force, to return towards the stationary platform 45 end ofapparatus 1. The vertical distance of the wearable tracking device 71from the floor, being referenced by horizontal line B, may now be largerby a distance of X when compared to the mid-repetition distance A. In anembodiment, device 71, using GPS, accelerometer or other technology maydetermine a difference in the vertical height of device 71. Thisvertical distance difference information may be then be used byapparatus 1 and/or device 71 to determine when an exercise repetition iscompleted.

The information from the tracking device 71 may be communicated to theinteractive exercise instruction system of apparatus 1 and displayed onscreen 73 indicating completion of repetition number six. Additionally,if the speed at which repetition number six was completed exceeded therecommended speed for the user to maximize the benefit of this exercise,screen 73 or another device (including device 71) may be used toinstruct or advice the exerciser to slow down.

In an embodiment, wearable tracking device 71 may be or include a bloodpressure or heart rate monitor. Based on the profile information of auser (which may be stored with apparatus 1, or otherwise accessible byapparatus 1 over one or more networks 6), apparatus 1 may make adetermination of the performance level of the exerciser based on thereal-time blood pressure and heart rate information received from device71 before/during/after the performance of an exercise.

In an embodiment, if the exerciser 70 is underperforming or not reachingtheir goal, the processor 2 may alert the user or change certainsettings on the Pilates apparatus 1 to increase the exerciser'sworkload. For example, if exerciser 70 is working at 65% cardiovascularcapacity when they should be working at 85% capacity for maximumexercise benefit, the processor 2 may alert the exerciser 70. Or, forexample, an automatic spring tensioning device may engage additionalsprings 44 affixed between the slidable carriage 43 and fixed platformend 45 of the apparatus 1, thereby forcing exerciser 70 to work at ahigher cardiovascular capacity to overcome the increased resistanceforce. Or, for example, if it is determined that the exerciser hassurpassed a physiological goal, the tension may be decreased to make theexercise easier for the user.

Pilates apparatus 1 may be adjusted to perform thousands of Pilatesexercises that position the exerciser in thousands of varying positionsupon Pilates apparatus 1. It is understood that the apparatus 1 may beused to instruct a user how to configure or adjust an apparatus 1,position themselves, and perform any applicable exercise, as well asperform the additional functions described herein.
